First time buying a car online.
First time buying a car online. Jeff Rick was great. He made the process easy and answered all my questions about the car. He sent me a video of the car as well. The purchase was quick and easy for being out of state. Just waiting for the car to be transported here which was also easy to set up. Thank you.

Reuben Floyd was incredibly helpful in guiding us toward
Reuben Floyd was incredibly helpful in guiding us toward our 2024 Rav4. He was patient with some of our indecision but once we got to writing it up, he was very efficient and thorough. He was also a very pleasant person that we got to know. He was focused and really cares about people. He's a very valuable employee and we are grateful that he took such good care of us!

I purchased a 2025 Ct4 Luxury from Delaware Cadillac in
I purchased a 2025 Ct4 Luxury from Delaware Cadillac in July 2025. I noticed some inconsistencies in the paint on the passenger rear quarter panel and the rear parking sensors were working intermittently. I contacted Tony in the service department, and she checked the problems I had. She scheduled an appointment with the paint service and had the parking sensors checked. The day I came in for the scheduled service, Mike checked my Ct4 again to make sure he saw the problems too be corrected. I was given a Ct4 to drive while the work was being done on my vehicle, this was helpful because its the same car and I did not have to figure anything out. Mike called and told me that the paint was worked on but he did not think it was any better than I had done with the touch up and the parking sensors were checked and seemed to be as they were supposed to be. When I arrived to pick up my vehicle, I was very happy with the paint work and the vehicle was clean as I left it. It is important to me that some one knows that I am very satisfied with the way this issue was handled . I want give kudos to Dane Tjaden for sales, Mike Anderson and Toni Spille for service. Thank you, I have never been treated this well by a car dealer. ( Cadillacs are more than a car!) T. A. Olin To Whom It May Concern, I purchased a 2025 CT4 Luxury from Delaware Cadillac in July 2025. Shortly after, I noticed some inconsistencies in the paint on the passenger rear quarter panel and found that the rear parking sensors were working intermittently. I reached out to Toni Spille in the service department, who promptly scheduled an appointment to address both concerns. When I arrived for the service, Mike Anderson inspected my CT4 again to confirm the issues and ensure everything would be addressed properly. I was provided with a loaner CT4, which I greatly appreciated—it made the transition seamless since it was the same model I’m familiar with. Mike later contacted me to provide an update. He informed me that while the paint had been retouched, he personally didn’t feel it was much of an improvement over my own previous touch-up. He also noted that the parking sensors were tested and found to be operating as expected. However, when I picked up my vehicle, I was genuinely pleased with the paint work—it looked much better than I anticipated. The vehicle was also returned to me clean and in great condition, exactly as I had left it. I want to express my sincere gratitude for the excellent customer service I received. It’s important to me that someone knows how satisfied I am with how this situation was handled. I’d like to especially recognize Dane Tjaden in sales, and both Mike Anderson and Toni Spille in service. Their professionalism, transparency, and care made all the difference. Thank you again. I have never been treated this well by a car dealer—and I firmly believe that Cadillacs are more than just a car! Sincerely, T. A. Olin

Found the car with the mileage we'd been looking for. Drove from Tallahassee, FL. to Ocala, FL. and Sullivan's to trade our existing car in on the 2019 Mercedes. In and out in just over 2hours. Gotta be a record for buying a car. Sullivan's was very efficient and professional. Highly recommend them for your next vehicle.
Beautiful and comfortable car
It is easy to navigate , good for gas, quiet but still shows the work of the engine. Warms up quickly and has luxurious look.

I want to take a moment to sincerely thank Cesar Rojas,
I want to take a moment to sincerely thank Cesar Rojas, Finance Manager, and Anthony, our Sales Representative, for an outstanding experience at Williamson Cadillac. We initially went in to look at an Escalade. While it is an impressive vehicle, we quickly realized we did not need something that large and wanted to stay within a comfortable monthly payment. As we stepped out of the Escalade, we noticed how many people were involved in selling it. That is when Cesar crossed our path, and the timing could not have been better. Cesar took the time to talk with us outside, gave us honest advice, and most importantly brought an incredible positive energy. No pressure, no sales tactics, just real guidance. I come from a BMW background, and I can confidently say that the team at Williamson Cadillac made us feel genuinely comfortable from the start. My wife then saw the Vistiq Premium Luxury and instantly fell in love with it, especially the celestial exterior and the phantom blue interior. That moment sealed the deal. I have been to many dealerships over the years, and I have never met a finance manager like Cesar. He gives you confidence, he listens, and he makes things happen. This is the first time I have ever worked with a finance manager who did not try to overload us with unnecessary packages. That alone speaks volumes. Anthony was also excellent throughout the process. Professional, patient, and supportive from start to finish. Together, Cesar and Anthony made this experience smooth, transparent, and actually enjoyable. This is our first EV, and we are excited to enjoy it throughout the lease. With the way we were treated, I truly hope we will be back in a couple of years to get into an Escalade IQ. If you are looking to purchase a vehicle and want a stress free experience, ask for Cesar Rojas and Anthony. You will not regret it. Thank you both for your commitment, honesty, and effort. It made all the difference.

Car size is good, considering the market for sedan
Plenty of room. I used the controls on the steering wheel. Never on console, sometimes on screen. Seldom take eyes off road. Had twenty months left on my XTS bumper to bumper . Next car was going to be CT6. I don't know what Cadillac is doing with sedans. There were no CT6 in Tampa had to go to West Palm but the CT4 and 5 were too small. The screen on the CT5 looked like it was slapped on top of dash and sun roof left something to be desired. Cadillac and sedan?????. looks like Electric in the future ?????

We felt comfortable through the whole process. Rich in sales did a great job and the gentleman in finance did as well. All questions were asked. We didn't feel the usual anxiety when buying a car.
Amazing...and American!
Recently bought a used CT6 w/2.0 Turbo (2018 with 39K miles). Have put only about 500 miles on it so far, but, WOW!!! This car is amazing! This car lives up to it's reputation as a builder of premium American luxury vehicles. My las t Cadillac was a 2000 STS...which was mediocre by comparison. It is soooo beautiful inside. I like that the screen is integrated into the dashboard. It's size takes a bit of getting used to, as my last car was a Mercedes E250. I test drove the 2.0 turbo and the 3.0, and found the 2.0 Turbo to be equally responsive but smoother. Exterior styling is simple clean and exudes luxury. I get so many compliments, heads turns and such. I love the Apple Car Play feature that projects what's on my phone to the in-dash screen. Recently did a road trip and got an AVERAGE of 33.4 MPG on the highway. I am getting 25 MPG+ around town. To me, that's pretty impressive for a car his size. In keeping with Cadillac's reputation, this car drives so smooth and quiet. Last time I drove a car this quiet and smooth as a Lexus LS460. At $30K less than the price of an average EV, it will take a lot of gas to make up the cost difference of those overpriced cars.

A Praise-Worthy American Luxuray Automobile
Having had my 2018 Cadillac CT6, equipped in the optional Premium-Luxury trim level, for nearly 3 years, I can honestly boast of its many attributes. It offers wonderful styling inside & out, the availability of virtually every current "high-tech" option conceivable, and has proven to be consistently reliable – and, while some may describe it as a bit “pricey,” it’s actually a relative bargain, when compared to its European competitors. The CT6 harkens back to the classic Cadillac sedans of years gone by, as its size, comfort, and luxury amenities remind owners and admirer’s alike, of many of those all-American classics. Although it's a pleasure to drive, even when equipped with the new and improved, 3.6L V6, the optional 3.0L Twin Turbo engine is recommended for those drivers who like a “little something extra” when depressing the accelerator pedal. With regard to performance, it is somewhat regrettable that an (optional) V8 is unavailable in the company’s “Flagship model.” This absence, I suspect, is a rather obvious "nod” to the so-called green energy movement that seems to have “infected” the entire auto industry, of late. In summary, if you’re looking for a full-sized American luxury car – look no further. The Cadillac CT6 “fits that bill, to a tee.”

The Perfect Luxury car
I purchased the CT6 Luxury AWD new in 2017. I haven't had any issues at all. I love the double sunroof and the 360 camera view. But what I am really upset about is GM discontinued this model. It is an awesome driving car and I won't be getting rid of it anytime soon.

Great value
Almost all options are included in a specified trim level so purchasing is straightforward. “Infotainment Center” has an overwhelming combination of great GPS navigation, electronics inter-connectivity, communications, and entertainment features. Enhanced safety features are impressive, from notices (visual and tactile) of cross-traffic backing out of driveway, to blind-spot warnings, following-distance display, etc.

I purchased the car new and have had it for 6 years, it has been nothing but awesome in many ways. The styling has endless elegance and will always be a good looking car. Being at "this time" possibly the last of the BIG BODY Cadillacs it will remain special in many ways. It is a great driving car with the combination of AWD ultimately makes it a year round car for my location.

Brad Arrington was the best! Everyone we dealt with was top notch. Who knows, someday we may drive 5 hrs just to come back. The Browns Gainesville Texas
Love my Red Shiny Cadillac
This car drives like a dream and the 3.6L Engine gives me that burst of power you really want when entering a fry. Love the Apple Play features that put all the apps from your phone on the screen, allowing me to listen to my audio books. The turn by turn navigation system is really nice and the screen location is just in the right place.

Amazingly smooth, well-made
I'm trading my 2019 CT6 after two years. Have really enjoyed this car. There is no better highway cruising car ever, it's incredibly smooth but tightly built, not sloppy ever. Great gas mileage, very peppy, and beautiful. The electronics are very easy to understand. The only complaint- driver's seat too short, I'm 5'11", long legs, and I had a buy a bolster cushion. Otherwise, I've loved it. Trading up to a BMW 8 series for more excitement.

Mr Kenneth Simms was the best Salesmen.
Mr Kenneth Simms was the best Salesmen. I didn't want all that normal Salesmen fluff. I wanted a car for my retired Mom who's car was recently totaled and I wanted it quick. I did my research, called with the exact car and my specs, and he LISTENED. He was patient, professional, and knowledgeable and above all accomodated our needs. Bottom line, he was selling a car and we were buying one. Mr Kenneth made the DEAL. Even delivered a car to my Mom in Gonzales, then met us at the dealership on his off day to deliver her actual vehicle. Thanks Mr Kenneth! God Bless.
